    Comment "The term 'aromatic' was assigned before the physical mechanism determining aromaticity was discovered, and was derived from the fact that many of the compounds have a sweet scent. The configuration of six carbon atoms in aromatic compounds is known as a benzene ring, after the simplest possible such hydrocarbon, benzene [ IATE:1566036 ]. Aromatic hydrocarbons can be monocyclic (MAH) or polycyclic (PAH)."
